I read somewhere that ‘Memory Free’ batteries are a better option? What exactly does it mean?

A Memory Free battery is less prone to memory effect. With a Memory Free battery, you don’t have to wait until the battery is fully drained to recharge it again. You can charge it as per your convenience. Most NiMH batteries including our Uniden BT-909 Compatible NiMH Battery are memory free.

Will charging my Uniden Bt-909 Cordless Phone Battery with a NiCd battery charger take a toll on the battery life?

Though NiCd battery chargers do charge NiMH batteries, you cannot expect the BT-909 battery to be charged to its fullest. Besides, NiMH battery chargers are designed in such a way that they prevent the formation of Hydrogen bubbles on the NiMH battery plates as opposed to NiCd battery chargers. So, eventually NiCd battery chargers can shorten the battery life dramatically or end up permanently damaging the battery itself.

My batteries become too hot to touch after charging. Can I minimize overheating? If yes, in what way?

It is quite normal for NiMH batteries to reach temperatures as high as 130 degrees upon charging. However, if you are too apprehensive about this temperature rise, then you can minimize it in two ways.

Try not to close the cover of NiMH charger while charging. This helps in dissipating as much heat as possible.

You can also use a small fan to prevent excessive heat buildup during charging.

I have not used my Uniden BT-909 Cordless Phone Battery for a long time and now I am having trouble as its performance is not up to the mark. How can I fix this problem?

If left unused, the Uniden BT-909 Replacement Battery has the ability to self-discharge within one or two months. So, before using the battery again, make sure you recharge it fully. However, to recapture its original performance completely, you’ll certainly need to condition the battery.

How eco-friendly is the Uniden BT-909 Battery?

The Uniden BT-909 Replacement Battery is 100 percent recyclable as they are free of toxic heavy metals like cadmium or lead. So, you don’t have to worry about environmental issues while disposing off such batteries. After the battery dies, just stash Uniden BT-909 Batteries on a landfill or leave it in a Battery Recycling Center.

My battery is just two months old. But, it seems to be running out of charge frequently. Do I have to replace the battery?

If the rechargeable battery is new, then try battery conditioning. To recondition your battery, leave the batteries in your phone and allow it to discharge fully. After the phone stops working, fully charge your batteries again. Repeat the power cycle two or three times to ensure complete battery exhaustion. When it’s completely exhausted, charge your battery fully and start using it. If the problem persists, then you definitely need a replacement. You can opt for the Uniden BT-909 Cordless Phone Battery that comes with 365 Day Power Performance Pledge from Batteries direct. So, you don’t have to worry about battery replacement at least for a year.
